U.S. stock futures edged lower Wednesday evening, extending a two-day Wall Street slide. The tech sector led declines as investors took profits ahead of TSMC's fourth-quarter earnings, a key barometer for global chip demand. Broader market sentiment was also dampened by geopolitical jitters surrounding potential U.S. intervention in Venezuela and Iran.

TSMC shares fell over 1% in U.S. trading, with the company serving as a bellwether for the semiconductor industry and a primary supplier to NVIDIA. The pullback in chips was broad, fueled by reports of Chinese restrictions on domestic sales of Nvidia products and a Reuters story claiming China ordered local firms to stop using U.S. cybersecurity software.

Bank stocks also weighed on markets following President Trump's proposal for a 10% cap on credit card interest rates. Executives warned the move could hurt consumers and returns, overshadowing strong quarterly results from Bank of America and Citigroup. Shares in Wells Fargo dropped after missing revenue estimates, while Oracle slid on a lawsuit from bondholders over its AI spending.
